Hillary Clinton, the frontrunner for the Democratic nomination for President, just received an endorsement from Eric Holder, the first African-American U.S. Attorney General.

Clinton’s campaign announced the endorsement in a statement to the Associated Press. Holder served President Barack Obama for five years in his position. “Our next president can’t shy away from building on the progress of President Obama,” according to his statement, “which is why Hillary Clinton is the candidate that we need in the White House.”

He’ll also reportedly hit the campaign trail on her behalf. According to the publication:

The former attorney general will campaign for Clinton in an upcoming swing to South Carolina, accompanying her to a state Democratic Party dinner Saturday and a Sunday debate sponsored by NBC News and the Congressional Black Caucus.
